Contract
| Field |
Bound contract |
| Trigger |
Explicit human invocation for repository onboarding or for creating or improving AGENTS.md to capture conventions, constraints, or rationale. |
| Authority |
Reversible local writes to the repository's AGENTS.md only; do not mutate any other file, version-control state, credential, or remote system. |
| Side effect |
Create or update AGENTS.md from repository files actually read, and identify descriptive lines for deletion; never fabricate a rule, constraint, rationale, or source. |
| Done |
AGENTS.md exists and every retained instruction is prescriptive, non-derivable from the repository itself, and grounded in evidence that was actually read. |
Inputs
Required: the repository root and explicit human invocation. If the intended AGENTS.md location is not the repository root, the target path must be supplied. Optional: conventions, constraints, or rationale supplied by the human; treat these as candidate instructions and distinguish them from repository-grounded evidence.
Procedure
- Resolve the repository root and the single target
AGENTS.md; reject a target outside that repository and make no mutation.
- Read the existing target when present, then inspect only repository files relevant to its candidate instructions, such as build and test configuration, manifests, automation, architecture boundaries, and nearby documentation. Record which files were actually read.
- Admit a candidate only when it tells a future agent what it must do, must not do, or must preserve. Reject repository descriptions, inventories, generated facts, and commands or settings that a future agent can derive directly by reading the repository.
- For each admitted instruction, identify evidence in a file actually read or mark it as human-supplied. Preserve rationale only when the evidence or human input establishes it; do not infer missing policy from common practice or invent evidence.
- Review the existing target line by line. Preserve grounded, non-derivable prescriptions; propose removal of descriptive, stale, duplicated, or directly derivable lines, naming the reason for each proposed removal.
- Write the smallest coherent
AGENTS.md that applies the accepted removals and contains only the admitted instructions. Keep each rule operational by stating its condition and required action or prohibition.
- Re-read the resulting target and verify every instruction against the admission gate and its recorded evidence. If any instruction lacks grounding or is derivable from repository files, remove it before declaring success.
- Report the target path, evidence files read, applied additions or changes, and removals. The rollback path is restoration of the target's pre-write contents, or removal of the newly created target when none existed.
Failure and recovery
- Invalid or ambiguous target: Make no mutation and return
blocked with the unresolved repository root or target path.
- Insufficient evidence: Omit the unsupported candidate. If no instruction survives, leave an existing target unchanged, do not create an empty target, and return
blocked: no grounded, non-derivable rules.
- Unsafe scope expansion: Stop before changing any file other than the resolved target and return
blocked with the out-of-scope change required.
- Write or verification failure: Restore the pre-write target contents when possible and return
blocked with the failed operation and whether rollback succeeded. If rollback fails, report the exact partial state; never claim the done predicate.
A partial draft is not success. Return it only as a partial result with unsupported candidates and unapplied removals identified.
Output
On success, the concrete artifact is the resolved AGENTS.md, accompanied by a report listing evidence files actually read, human-supplied rules, applied additions or changes, applied removals with reasons, and the rollback path. Otherwise, output the exact blocked classification and any partial-state or rollback details required above.
